Patented Mar. 18, 1950 NET FRANK J. LASAR, OF SAN FRANCISCO, CALIFGBNIA, ASSIGNOR TO CHAMPION WASHER COMPANY, L'ID., A CORPOBATIGN OF NEVADA WASHING Application filed May 21,

My invention relates to improvements in washing machine construction wherein actuating mechanism is mounted within and upon a housing bracket secured upon a wall above a stationary wash tray and arranged to re ciprocate an agitating element within the tray.

The primary objectof the present invention is to provide an improved washing ma- 0 chine construction whereby an agitating element may be efficiently operated directly in a wash tray.

Another object is to provide an improved means for mounting actuating mechanism within a housing bracket to afford increased strength and rigidity, and to render the machine more durable and efficient.

A further object is to provide an improved actuating mechanism adapted to permit an efficient operation of the machine at increased speed.

A still further object is to provide an improved machine in which the actuating gears a may be caused to run in grease without danger of permitting grease to leak into the tray of materials being washed.

I accomplish these and other objects by means of the improved device disclosed in to the drawings forming a part of the present application wherein like characters of reference are used to designate similar parts throughout the specification and drawings, and in which,

Fig. 1 is a front elevation of my improved washing machine,

Fig. 2 is a rear elevation of the machine, and

Fig. 3 is a vertical section of the machine.

Referring to the drawings, the numeral 1 is used to designate in general a housing bracket, the upper portion of which is substantially circular and provided with a flange 2 whereby the bracket may be secured directly upon the wall or other supporting structure directly over an ordinary wash tray 3. The bracket is provided with a downwardly disposed extension 1- having a slot 6 in the front thereof. A pair of guides 7 are mounted within the bracket extension 4 upon op- MACHINE 1927.

posite sides of the slot 6 to receive a crosshead 8 slidably mounted thereon and having an arm 9 extending outwardly through the slot in the front of the bracket. An agitating element comprising a plurality of suction cups 11 mounted upon a common stem 1.2 by means of a vane plate 13 is detachably and adjustably secured upon the arm 9, said agitating element being arranged to be reciprocated within the tray 3 by means of the cross-head 8.

A shelf 14 is formed integrally with the housing bracket 1. to form a support for a motor 16 secured thereon and controlled by a suitable two way switch 17 electrically connected in the well known manner between the motor and a source of electrical energy, not shown. I

A gear box 18 comprising a body provided with lugs 19 formed around the edges flush with one face thereof is secured against the inner surface of the front of the housing bracket 1 by suitable securing members 21. A drive shaft 22 is ournaled within the upper portion of the box 18, said shaft being supported within enlarged bearing blocks formed within the upper corners of the box and extending outwardly through one side of the box. A flexible coupling 23 is connected between the shaft and the motor shaft through an opening formed in the side of the housing bracket.

A worm 24 is mounted upon the shaft 22 and arranged in meshing relation with a worm gear 26 mounted upon a worm gear shaft 27 journaled upon the box 18, the forward end of the shaft 27 extending through the front of the box 18 and the housing bracket 1 while the rearward end of the shaft 27 extends outwardly through a cover plate 28 closing the back of the box 18. A crank 29 is mounted upon the rearward end of th shaft 2? outside of the box, and a connecting rod 31 is connected between the crank and the cross-head v8.

The gear box 18 is constructed and the gears and shafts assembled therein entirely inde pendently of the housing bracket 1, the box being packed with grease before the cover plate 28 is secured in place upon the back of the box. The lugs 19 are distributed around the edge of the box so that the load is distributed over a large area of the bracket, whereby the box, which'is preferably made of cast iron, maybe rigidly supported upon the bracket, which ismade of cast aluminum, without imposing undue strain upon'any portlon of the bracket or the securing members.

improvement over Washing machine constructions of the present type, wherein the shafts are journalled directly in the aluminum'mounting bracket and the strain and wear is so greatthat the machine can be operated only at low speed, and wear. and disrtortion is so great that the machine is of relatively, short life. Furthermore, my improved constructlon permlts the gears to run 1n comprising a mounting bracket formed from light, soft metal; an independently construct- I A drive mechanism for washing machines ed gear box formed from relatively heavy,

a power driven shaft journalled within the,

grease or oil at all times, thereby obtaining a Y nolseless operatlon free from wear without permitting any possible leakage of oil or Y I grease into the wash tray. vVhen once asc 7 sembled, the gear box and gears will insure an efficient operation indefinitely without further care or attention. V

Inoperation, the motor is driven to rotate .the crank arm. 29 and thereby reciprocate the'cross-head 8 and the agitating element in the obvious manner. The'rigid mounting obtained insures a quiet and efiicient operation substantially free from vibration, and

I permits the agitating element to be operated vat arelatively high speed whereby a rapid and efficient washing of clothes or other materials may be effected.
